Thorium-230 coral chronology of a late prehistoric Hawaiian chiefdom

Documenting the history of settlement in Hawaii during the last few centuries before European contact, is crucial to charting the evolution of the most complex chiefdom in Polynesia. It is precisely this period that Hawaii, and many Polynesian societies, underwent their most rapid changes in political, economic and social organisation. The last ∼500 to 300 years in the ¹⁴C calibration curve is problematic with wide fluctuations often rendering large age spans that do not precisely date single events, especially troubling with a culture-historical record of ∼1000 years duration. Here we present an extremely high precision ²³⁰Th chronology for archaeologically constrained coral samples from a range of occupancy sites. Our high precision dates allow the time of site use to be clearly demonstrated. They also provide the first dates for habitation sites in Hawaii that clearly show contemporaneous occupation—the major problem in settlement pattern archaeology. We demonstrate that two sites were occupied within the same year. Our refined chronology, provides new and exciting opportunities for tracking sociopolitical and economic developments during the last few centuries—the crucial period in the evolution and transformation of Polynesian societies.     

The Prehistory of the Tibetan Plateau to the Seventh Century A.D.: Perspectives and Research from China and the West Since 1950

Until recently, there has been no sense of a Tibetan prehistory. Beginning in the 1970s, however, Chinese archaeologists began to systematically explore the plateau, and began to draw an outline of the deep Tibetan past. The pace of research accelerated rapidly in the 1990s, which brought this outline into sharper focus. This paper reviews what is known of Tibetan prehistory until the seventh century A.D., when the Tibetan empire was established. Topics covered in this paper include a consideration of the antiquity of a human presence upon the plateau, changing adaptive strategies following the end of the glacial epoch, the advent of the Neolithic, and the emergence of social and political complexity. Despite significant advances in our knowledge of the Tibetan past, much work remains to be done before models of process can be examined in any detail.     

Multiple pathways across past landscapes: circuit theory as a complementary geospatial method to least cost path for modeling past movement

The incorporation of geospatial technologies in archaeology has resulted in productive advances in the analysis of past behavioral processes. Archaeologists have relied on the Geographic Information Systems (GIS) application of cost surface analysis and the computation of least cost paths (LCP) to study movement, one key social process. Recent research has identified limitations with LCP for modeling nonhuman species movement, notably the inability of LCP to accommodate multiple pathways. Archaeology must consider the implications of these critiques for models of past human movement. In this paper, I apply a different approach, circuit theory modeling, enacted through the program Circuitscape, to an archaeological case study previously analyzed with LCP modeling, travel to a regionally significant ceremonial earthwork center during Late Prehistory (ca. AD 1200–1600) in the Northern Great Lakes. Through this comparative analysis, I evaluate the advantages and disadvantages of these methods for modeling past movement. The results suggest LCP modeling and circuit modeling offer archaeology complementary geospatial methods for conceptualizing past mobility. Combining circuit theory and LCP allows archaeologists to produce richer models of past movement by appreciating scenarios where multiple pathways are important as well as scenarios where optimum single travel routes have priority.

Modeling Late Copper Age demographics on the Great Hungarian Plain using ceramic petrography

Ceramic petrography can be an effective method for studying demographic shifts and the possibility of migration into a region. This is based on the principle that ceramic manufacturing technology is resistant to change over time, while form and decoration can change quickly even in times of demographic continuity. As such, sudden shifts in raw material preparation and methods of pottery manufacture may be indicative of the arrival of new people in a region. The manufacturing characteristics indicative of such a demographic change are observable and measurable microscopically. Petrography was used to describe and measure paste characteristics of 114 Middle Copper Age, Late Copper Age, Early Bronze Age, and Middle Bronze Age sherds from the Körös region of the Great Hungarian Plain to determine if changes in manufacturing techniques accompanied changes in ceramic form and decoration at the beginning of the Late Copper Age Baden period (ca. cal. 3500 B.C.). A comparison of the petrographic results from the cultural phases showed that little manufacturing and technology change occurred during the time period covered by the study. Migration of new people into the region is therefore not supported, and changes in ceramic form and decoration associated with the Late Copper Age occurred during an extended period of demographic continuity.     

The cultivation of perennial rice,an early phase in Southeast Asian agriculture?

Domesticated rice, Oryza sativa L., though a perennial, is nowadays usually cultivated as an annual. This has led a number of commentators to misinterpret the historical record. The older view that rice was domesticated around the Bay of Bengal and in parts of mainland Southeast Asia has been replaced by competing views of earliest domestication in that region and in the Yangzi valley. Botanical considerations point clearly to the retention of perennial characteristics while archaeological and historical evidences point to cultivation with more than a single harvest from an initial planting – the practice of ratooning. Evidence is reviewed briefly for China and more extensively for Southeast Asia. Modern field evidence is used to support the notion that ratooning was probably more widespread in the past and that this practice may represent an early phase in the history of rice agriculture in Southeast Asia as it does in China.

THE TWILIGHT OF THE GODS? GENOMIC HISTORY AND THE RETURN OF RACE IN THE STUDY OF THE ANCIENT MEDITERRANEAN

This article discusses the impact of genomic history, a subdiscipline that emerged in the study of the ancient Mediterranean in the 2010s. In 2014, scientists first published a method for extracting genetic material, which they christened aDNA (ancient DNA), from ancient human remains in hot climates. After a decade of research, genomic history is now poised to transform our understanding of Mediterranean premodernity, centering migration and conflict as the key mechanisms for cultural change. Despite years of critique, aDNA researchers have failed to seriously examine the bioessentialist assumptions implicit in their work—a failure that has led many to deploy language that is strikingly evocative of pre-World War II racialism. Even worse, some genomic historians continue to make troubling overtures toward the ethnonationalist Right, which has been ascendant across Europe and North America since the 2010s. This article traces the intellectual genealogy of genomic history from World War II to the present, examines recent attempts to answer criticism from the humanities and social sciences, and suggests paths for responsible use of aDNA in historical and prehistorical scholarship.     

Stable isotopes in human skeletons of Southern Ontario: reconstructing Palaeodiet

Most native plants of Ontario use the C₃ photosynthetic mechanism and therefore have relatively low ${}^{13}\text{C}{}^{12}\text{C}$ ratios; maize is a C₄ plant and is relatively enriched in ¹³C. The proportion of maize in the diet of a human can therefore be estimated from the ¹³C-content of collagen of fossil bone. We have used this method to follow the increase in consumption of maize in ancient native populations over the interval from AD 400 to 1650, and to quantify the amount of maize consumed. Maize consumption rose gradually to a maximum of 50% of the diet by AD 1400. These data agree with archaeologically derived data for this region, and with previous isotope studies in the northeastern U.S.A. In some of the latter, however, the maximum percentage of maize consumed has been overestimated because maize was assumed to have a δ¹³C value of ?12·5‰; our studies of archaeological specimens show the correct value to be closer to ?9‰. The introduction of beans into the native diet about AD 1100, should have caused a decrease in the ¹⁵N content of human bone collagen because legumes are deficient in this isotope, with respect to meat and fish. However, we observe no significant change in the ${}^{15}\text{N}{}^{14}$N ratio of human bone collagen over the period from 2300 BC to AD 1640. We conclude that meat and fish remained the main sources of protein even after the advent of agriculture into this region.
